Synopsis
A front to our south today will lift northward tonight into Monday
morning as a warm front. A cold front is expected Monday night as an
area of low pressure moves into the great lakes region. This low
will drift northeastward across eastern canada through mid week.

Another low pressure system will lift out of the lower mississippi
valley towards the mid atlantic by late in the week.

Near term /until 6 pm this evening/
A front is nearly stalled just to our south. Meanwhile, high
pressure is across southeastern canada to new england then extends
to off the mid atlantic coast. This will continue to allow for an
onshore flow, resulting in a much cooler day compared to yesterday.

There is a lot cloudiness across the area, although breaks have been
occurring as the onshore flow is battling some drying that is
working in from the north and northeast. The nearby 12z raobs show
the moist layer is fairly thin, and the onshore flow is mostly below
3000 feet where it shifts and becomes southwesterly above this
level. The visible satellite imagery shows the cloud movement is
from southwest to northeast, although there appears to be a
convergence band of clouds near the CAPE may county coast and
delaware beaches eastward. Overall enough breaks are resulting in
some warmer temperatures inland and therefore the high temperatures
were increased at least a few degrees for many locales. Temperatures
should lower some this afternoon especially closer to the coast
given the onshore flow.

There is a burst of low-level warm air advection to our northwest
along with a weak short wave. There continues to be some convection
with this, however this is tracking to our west and north. While an
isolated shower cannot be ruled out mainly for the southern poconos,
looks like chances are much better to our north and west.

The hourly temperature, dew point and wind grids were adjusted based
on the latest observations. The temperatures were increased some
based on trends and some assistance from the hrrr.

Short term /6 pm this evening through 6 am Monday/
The frontal boundary to our south is expected to begin lifting
northward as a warm front overnight tonight into Monday morning. As
the front begins to lift into our area after sunset and overnight, a
couple of short wave/vorticity impulses are forecast to move across
the area as well. Typically with a warm front lifting across the
area, we would expect fog to develop, and possibly become dense. But
with the short wave/vorticity impulse, there will be some lift
across the area and there is the potential for some showers to
develop. With this turbulent air and a steady enough of a breeze,
while there will likely be some fog develop, we do not have any
dense fog forecast at this time. Another possibility overnight in
addition to the light fog is for some patchy drizzle to form. This
would most likely be for the northern half of the area north of the
lifting warm front.

Long term /Monday through Saturday/
Monday... Increasing southerly flow is expected in advance of the
cold front Monday night. This will enhance the warm air
advection that will already be occuring in the wake of the warm
front tonight. Thus, expect temperatures to be 10 to 15 degrees
above normal, with highs generally in the 70s and low 80s.

Depending on how quickly the ridge moves further off shore and
how quickly the cold front approaches the region, we could start
to see showers and storms propagate into eastern pa late in the
day.

Monday night... Cold front still on track to sweep through the
region late Monday night. Given the timing of the frontal
passage, low level lapse rates will be limited just ahead of the
front, which will limit instability (though there may still be
some surface based cape). However, 0-6km shear values will be
relatively high... On the order of 40 to 60 kt. This could lead
to a low cape/high shear set up for severe winds. However, this
is far from certain as if the inversion Monday night is stronger
than model soundings currently show, this could inhibit strong
winds mixing down to the surface altogether (similar to what we
saw with the storms last night). Additionally, precipitable
water values in the warm sector will be quite high. Expect the
threat for heavy downpours will be quite high, but the fast
storm motions should limit the flooding threat to poor drainage
areas.

Tuesday and Wednesday... In the wake of the cold front,
temperatures will be about 5 to 10 degrees lower, with highs
generally in the 60s and 70s. Models have trended faster with
the dry air advection behind the front, so I trimmed back on
the pops on Tuesday. It is looking mostly dry both days.

Thursday through Saturday... A warm front is expected to lift
north through the region Thursday or Thursday night. This will
be the start of the unsettled late week pattern. The biggest
question with this pattern is the evolution of the mid and upper
level low. The previous ECMWF showed the low becoming cutoff
over the lower mississippi valley. However, with the 00z run, it
has come closer to the GFS (which has stayed relatively
consistent with the last few runs). Both models depict the low
closing, deepening, and intensifying as it lifts northeast
through this period. However, there remain large differences in
the track and timing. For now, have stayed close to the previous
forecast and a consensus of guidance, with mostly medium chance
of precip, except Thursday night into Friday, with likely pops.

Aviation /16z Sunday through Thursday/
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

This afternoon...VFR ceilings near 4000 feet should lower to near
2500 feet later this afternoon. Confidence regarding lower
ceilings remains less than average as there is some drier air
working into parts of our region from the north-northeast. East
to southeast winds mainly in the 10-15 knot range, with some
local gusts to around 20 knots at times.

Tonight... MVFR ceilings are anticipated to lower to ifr this evening
(locally lifr overnight) as a warm front gradually shifts northward.

Some fog and drizzle should develop, however the extent of this is
less certain at this time. Visibilities are currently forecast to
lower into the 1-2sm range overnight. Some improvement may take
place toward morning especially at miv and acy as the warm front
shifts northward. East or southeast winds mainly 4-8 knots.

Outlook...

Monday... Ifr/MVFR conditions should be present to start at most
terminals, then improving toVFR by late morning. South to southwest
winds increasing to near 15 knots, with gusts 20-25 knots in the
afternoon.

Monday night... Widespread MVFR or ifr conditions with thunderstorms
likely. An abrupt wind shift to westerly is expected with a cold
front Monday night.

Tuesday and Wednesday... MostlyVFR conditions expected.

Thursday... StartingVFR, but may lower to MVFR as showers and
thunderstorms start to move into the region.

Marine
A front has settled to our south and will stall today before
gradually shifting north tonight and Monday morning as a warm
front. Northeast winds will turn easterly through the day with
gusts at times to around 20 knots.

North of the front tonight winds will remain easterly, but south of
the front the winds will become southerly. It is possible the front
may clear all of the waters during the overnight. While winds may
not reach advisory criteria, seas may begin building through the
night, but especially toward daybreak Monday. Overall, the
conditions are expected to be below advisory criteria through
tonight.

Outlook...

Monday and Monday night... Building seas and increasing winds
are expected by Monday morning. Southerly gusts near or above 30
kt are possible Monday evening on the coastal waters. On the
delaware bay, there is a bit more uncertainty, but sca
conditions are possible.

Tuesday... Winds will shift to southwesterly and then westerly behind
a cold front expected early Tuesday. Gusts on Tuesday may linger
near 25 kt. Elevated seas may linger into Tuesday night.

Wednesday and Thursday... Winds and seas are expected to stay below
sca criteria.
